IMATEST Test Charts Test Charts

Dynamic Range Charts : Our dynamic range charts are designed to test tonal response, noise, basic resolution and color.
When used with the Stepchart module, a high range of density levels may be tested.
Dynamic range charts are supported by the ​ Stepchart ​ , ​ Multicharts ​ and ​ Multitest ​ modules and
can be used with the ​ Dynamic Range ​ postprocessor if several manual exposures are available.
Dmax >= 3.4 is sufficient for camera phones and digital cameras with small pixel sizes, but
high­end DSLRs generally have higher dynamic ranges (and also manual exposure), which
makes them well suited for Dynamic Range.

24‐Patch Transmissive Color Target:The 24­Patch Transmissive Color Target can be used for evaluating color accuracy using a
lightbox, which can be more compact and uniform than a reflective lighting system.
These targets are produced with high­precision Light­Valve Technology. Custom reference files
are provided with each chart to ensure accurate color measurements. Customers using small
field of view systems or testing at close distances will benefit from these small and precise
targets.
Standard sizes are Small, 117.5 x 93.345 mm (4.625 x 3.675”), and Medium, 177.8 x 235 mm (7
x 9.25”). Custom sizing as small as .35 x .5” is available.

ColorGauge + Rez Checker: Use the miniaturized ColorGauge and Rez Checker for close range measurements of color,
tone, exposure error, white balance and noise. These charts are of particular interest for
medical imaging, especially endoscopes.
At center are 12 spectrally neutral gray patches to assess correct exposure and white balance
in close­up or macro photography applications.
